Abstract
The utility model discloses a ballpoint pen with a pen point capable of being prevented being broken. The ballpoint pen is characterized in that two cylindrical through holes are formed in a pen holder (1); a pen barrel (1) is mounted at the left end of the pen holder (10) and is in threaded connection with the pen holder (10); two elastic sheets (6) are mounted on the pen barrel (1) and fixed to the pen barrel (1) by bolts (4); cylindrical clamping columns (7) are mounted on the two elastic sheets (6) and positioned in the two cylindrical through holes in the pen holder (10) respectively; a pen core is mounted in the pen barrel (1) and the pen holder (10); an annular groove (9) is formed in the pen core; a cylindrical plate (11) is mounted on the right end surface of the pen core; a cylindrical pressing column (12) is mounted on the right end surface of the pen cylindrical plate (11) and positioned in a central hole in a smaller annular plate of the pen holder (10); and a spring (3) is mounted at the periphery of the pen point of a pen head (5). The ball point of the ballpoint pen automatically retracts into the pen barrel when not writing.
Description
Technical field
The utility model relates to a kind of ball pen, specifically a kind of ball pen that prevents to break nib.
Background technology
People often when temporary transient interruption is write, are not covered pen container on the penholder.Like this, if let pen fall on the ground because of carelessness, then nib is broken easily.Although people hope to have a kind of pen when pen falls earthward, automatically nib to be reduced to penholder inside, also do not see that this pen of breaking nib that prevents comes out at present.
The utility model content
The purpose of the utility model is the shortcoming that overcomes existing ball pen, and a kind of ball pen that prevents to break nib is provided.
The technical scheme that the utility model adopts is: said a kind of characteristic that prevents to break the ball pen of nib is: penholder is set; Said penholder is that the long cylindrical shell of the cylinder bodily form of horizontal direction and less annular plate connect into integral body by axis; Said less annular plate is positioned at the right-hand member of the long cylindrical shell of the said cylinder bodily form, and the left end of the long cylindrical shell of the said cylinder bodily form has external screw thread; Two cylinder bodily form through holes are set, the axis normal of said two cylinder bodily form through hole coaxial lines and their axis and the long cylindrical shell of the said cylinder bodily form on the said penholder; Pen container is set, and said pen container is that the cylinder bodily form short cylinder of horizontal direction and bigger annular plate connect into integral body by axis, and said bigger annular plate is positioned at the left end of said cylinder bodily form short cylinder, and the right-hand member of said cylinder bodily form short cylinder has internal thread; Said pen container is installed in the left end of said penholder by being threaded; Two screwed holes are set, the axis normal of said two screwed hole coaxial lines and axis and said cylinder bodily form short cylinder on the said pen container; Two flexure strips are installed by bolt on the said pen container, said bolt is installed in the said screwed hole; A cylinder bodily form card post respectively is installed on said two flexure strips, and said two cylinder bodily form card posts lay respectively in two cylinder bodily form through holes of said penholder; Pen core is installed in said pen container and the penholder; Said pen core is made up of core bar and the nib that is positioned at the left end of core bar; Said core bar connects into integral body by a less cylinder bodily form cylindrical shell that is positioned at the left side and a bigger cylinder bodily form cylindrical shell that is positioned at the right, and the right-hand member of said less cylinder bodily form cylindrical shell is provided with a cannelure; A cylinder bodily form plate is installed on the right side of the bigger cylinder bodily form cylindrical shell of said pen core, a cylinder bodily form is installed on the right side of said cylinder bodily form plate is pressed post, the said cylinder bodily form is arranged in the centre bore of the less annular plate of said penholder by post; The spring that it is horizontal direction that the nib of said nib is installed a center line on every side, the left end of said spring contacts with the right side of the bigger annular plate of said pen container, and the right-hand member of said spring contacts with the plate object of nib.
Positive meaning: when not writing, in the automatic indentation pen container of the nib of ball pen.Even ball pen is fallen on the ground, nib can not contact with ground yet, has protected nib.
